A pedestrian-vehicle crossing device based on a moving walkway and its control method

Abstract

The invention discloses a pedestrian-vehicle street crossing device based on a moving walkway and a control method thereof, mainly comprising a first pressure plate, a second pressure plate, a third pressure plate, a fourth pressure plate, a first moving sidewalk, and a second moving sidewalk and the controller, the four pressure plates are respectively set in the pedestrian and vehicle waiting areas on the four sides of the crosswalk, and the quality signals of the pedestrians and vehicles are transmitted to the controller; the two moving walkways are horizontally and symmetrically arranged on both sides of the center line of the pedestrian crosswalk, and the controller controls the automatic The opening and closing of the sidewalk and the running direction; the invention has three working modes: normal working condition, vehicle priority working condition and pedestrian priority working condition, and the switching of the green light passing time of each passing direction can adapt to the real-time pedestrian and vehicle traffic conditions, It alleviates the problems of fewer people and more vehicles, vehicles waiting for the green light and more people and fewer vehicles, pedestrians waiting for the green light. At the same time, the use of moving walkways reduces the time for pedestrians crossing the road to reach the opposite side of the road after the green light ends, and improves the utilization rate of pedestrian crossings. .

Description

technical field [0001] The invention relates to a management device for pedestrian-vehicle crossing, in particular to a pedestrian-vehicle cross-street device based on a moving walkway. Background technique [0002] In the process of people and vehicles existing in China passing through the crosswalk, there are often problems of fewer people and more vehicles, vehicles waiting for the green light, more people and fewer vehicles, pedestrians waiting for the green light, and pedestrians passing the crosswalk at a slow speed. The inflexible switching of the green light time of the traffic lights in each direction of traffic leads to a long blank period in the crosswalk. Pedestrians pass the crosswalk at a slow speed and take a long time. This process is likely to cause a backlog of vehicles in the vehicle waiting area and further cause traffic congestion.

AI Technical Summary

Problems solved by technology

The green time switching of the traffic lights in each direction of traffic is not flexible, so that there is a long blank period in the crosswalk, and the speed of pedestrians passing the crosswalk is slow and takes a long time. This process is likely to cause a backlog of vehicles in the vehicle waiting area, further causing traffic congestion

[0003] Chinese patent "Application of wireless new electronic license plate to realize the system and method of traffic intersection guidance" (application number: 201710171266.6), Chinese patent "control method of traffic lights at road traffic intersections" (authorization number: CN105303850B) and Chinese patent "Assisting vehicles to speed up "Intelligent Traffic Signal Control System and Method for Crossing" (Application No.: 201710267844.6) both collect vehicle information on the road section, determine the number of vehicles passing through the intersection, and use the controller to control the time of traffic lights to improve the traffic in the direction of the vehicle. The flexibility of signal light switching alleviates traffic congestion caused by vehicles, but does not optimize the time of traffic signal lights in the direction of pedestrians, and fails to shorten the blank period of traffic intersections caused by pedestrians crossing the street. Only the time required for vehicles to pass is considered. Single range, easy to cause traffic accidents

[0004] Chinese patent "Distributed Intelligent Traffic Signal Control Method and Device Based on Back Pressure Routing Algorithm" (Application No.: 201711418924.3) According to the pressure difference between the entry intersection and exit intersection corresponding to each traffic route, the calculation at each intersection can ensure The traffic signal scheduling strategy for maximum traffic pressure release, based on which the traffic signal scheduling is carried out, realizes the distributed urban intersection coordinated scheduling with the optimal total passing traffic flow in the road network, but does not set the upper limit time for the traffic signal time in the direction of the vehicle. When it is located on a traffic-congested road section, it is easy to cause vehicles in the direction of the initial green light at the intersection to be in the traffic state during the time period until there is a blank period in this direction, which may easily cause congestion of vehicles in other directions.

[0005] The Chinese patent "Independent adaptive traffic signal control system and its implementation method" (application number: 201410338285.X) and the Chinese patent "a traffic signal control method based on real-time traffic information" (application number: 201710846760.8) are based on the actual traffic Traffic flow is used to regulate the duration of green lights in each direction, which alleviates traffic congestion. However, the upper limit of the duration of green lights is not set, which will easily cause imbalance in each direction of traffic and cause traffic congestion. At the same time, the speed of pedestrians cannot be optimized. Shortening the blank period caused by the slow speed of pedestrians is not conducive to the protection of pedestrians' personal safety
